If you can solve a problem in fewer lines of code, do it and you definitely did that @daviddamilola. Thanks for participating in Week 1 of Algorithm Fridays.

I really like that your solution takes care of possible null values for input by setting a default value of the array to be an empty array.

The only question I have is, is there a way we could have solved this problem without using another data structure?

I have posted my solution here, let me know what you think.
